Wonder if there is some way for the commoner to
test? Take a quart, and see how many drops of
water before one settles to the bottom? Some
simple thing like that?

Water mix, and shows different cloudy level.

I heard that during WWII the mustang fighters [P-51] were outfitted with
small spray of water droplets into the cylinders. The steam generated
extra boost and when activate, the pilot just 'took off' and left standing
anyone around. Two downsides were tended to blow the rings [well, duh!]
and if you didn't 'purge' your engine out afterward by running a decent
amount of time, the moisture vapor got deposited everywhere and 'rotted'
the engine out.

Note that the 707 and DC-8 (and military derivitives) used water injection
to increase jet engine thrust (and increased HC emissions). The B-52 would burn
5 tons of water (mixed with methanol) on takeoff with the old PW J-57's.
